It's not sure what's bothering Heath, as he was healthy for the final seven games of 2017. Heath has worked as a depth lineman for the last two years, but he is slated to start opposite J.J. Watt on the Texans' defensive front in 2018.

Heath (knee, illness) will not carry an injury designation into Monday's game against the Ravens.

Heath has been battling the knee injury for a few weeks, but it appears the undisclosed illness is what kept him sidelined at Friday's practice. Regardless, the 24-year-old appears ready to go for a depleted Texans' front seven that needs as much help as it can get.
